Calculate the principal value of (1+i)(1+i)(1+i)^{(1+i)}(1+i)(1+i).
e−π/4(cos(ln22)+isin(ln22))e^{-\pi/4}(\cos(\frac{\ln 2}{2}) + i\sin(\frac{\ln 2}{2}))e−π/4(cos(2ln2)+isin(2ln2))
eπ/4(cos(ln22)+isin(ln22))e^{\pi/4}(\cos(\frac{\ln 2}{2}) + i\sin(\frac{\ln 2}{2}))eπ/4(cos(2ln2)+isin(2ln2))
e−π/4(cos(ln2)+isin(ln2))e^{-\pi/4}(\cos(\ln 2) + i\sin(\ln 2))e−π/4(cos(ln2)+isin(ln2))
